Zimbra Skin command error

[samuel.lao85]

Hi folks,

I´ve been trying to change a logo for another domain in our zimbra server.

I know zimbraskinlogologinbanner could do that, but when I try to enter it I get an error:
ERROR: account.INVALID_ATTR_NAME (invalid attr name: [LDAP: error code 17 - zimbraskinlogologinbanner: attribute type undefined])

This is the comlete command I´m entering:
zmprov md domain.net zimbraskinlogologinbanner image.png
I´m writing it inside /jetty/webapps/zimbra/skins/_base/logos where is located image.png

Regards,

Samuel
